Quantum tomography of inelastic electron scattering \emph{via} orbital angular momentum states
Amir H. Tavabi, Alessio D'Errico, Paolo Rosi +10
The physical properties of a quantum system, whether pure or mixed, are described fully by its density matrix. Recovery of the density matrix through projective measurements -- ref…
Contrast enhanced imaging through weakly scattering media with spatially entangled photons
Alessio D'Errico, James Hubble, Rojan Abolhassani +4
Improving the image contrast of objects immersed in weakly scattering media can be achieved using various strategies. One common approach is to reject events associated with scatte…
Single-acquisition tomography of photonic qubits with structured media
Francesco Di Colandrea, Yingwen Zhang, John Grace +3
Quantum state tomography is an essential tool for characterizing quantum systems and underpins nearly every experimental realization of quantum technologies. Conventional tomograph…
Single-Image Entanglement Verification with Spatially Encoded Measurement Contexts
Nazanin Dehghan, Alessio D'Errico, Yingwen Zhang +3
Entangled photon pairs produced by spontaneous parametric down-conversion exhibit rich spatial entanglement structure that is often difficult to probe with conventional measurement…
Three-fold coincidence by stimulated parametric down-conversion
Yishai Klein, Alessio D'Errico, Farid Ghobadi +4
Parametric down-conversion is a widely used source of nonclassical light in quantum optics and photonic quantum technologies. While stimulated parametric down-conversion with stron…
Imaging Walk-Off Driven Distortions in EPR Photon Pair Correlations
Christian Howard, Roohollah Ghobadi, Nazanin Dehghan +2
Spontaneous parametric down-conversion is the primary source of position-correlated and momentum-anticorrelated photon pairs that form the canonical Einstein-Podolsky-Rosen (EPR) s…
